This invention relates to a carton or supporting container for fragilearticles such as radio tubes and the like.

An object of the invention is to provide a" container of simpleconstruction for resiliently supporting an article and for locking thearticle therein against removal. 4

Another object of the invention is to provide a simple and effectivecarton in which an article may be enclosed and locked against removalwithout visible evidence appearing on the carton. H

A further object of the invention is to provide a carton having closuresadapted to be locked to prevent removal of the article without adestruction of the locking means.

Other objectsand advantages of the invention will be apparent from thefollowing description.

In the manufacture of radio tubes, it has been found that when suchtubes are placed in a carton and sold, it often, happens thatunscrupulous intermediate selling agents will remove the article andsubstitute therefor one of inferior or defective character.

It has been proposed to provide a carton which might be sealed by anadhesive covering but it is desirable to be able to test the article, asfor example, a radio tube, without removing the same from the container.Furthermore, it is an advantageto be able to have visible indication ofthe operativeness of the article as by the light emitted from thefilament when the device is tested without making it necessary to removethe article from the packing.

In addition to the above, a carton containing an' article such as aradio tube must be so constructed as to resiliently support thetube.general handling or distribution.

The present invention provides a carton composed of an inner and outermember, the inner member being constructed to receive tion into theouter member. When a tube is positioned in the inner member, the samemay be inserted in the outer member and means associated with bothmembers operate to'lock the inner member from removal but. permit toprevent breakage during impacts in the and support a tube and adaptedfor inser- 1927.

the same to have-relative movement within the outer member. By reason ofthis construction, a tube may be placed in a carton and wholly enclosedby the outer member or casing and may be moved longitudinally thereof soas to expose the contact members of the tube to permit the same to beapplied to a socket for the through the device. The construction is soarranged that the upper portion of the tube is also exposed so that avisible indication passage of electrical current ma be had as to thelighting of the filament.

adio tubes enclosed in containers constructed in accordance with thepresent invention, although capable of being tested, are locked againstremoval since upon insertion of the inner member into the outer member,

suitable projections or obstructions on both members becomeautomatically engaged and prevent a removal'of the article without adestruction of the container.

The invention will be more fully understood by reference to theaccompanying drawings in which:

Fig. 14 is another modification of the looking means and Fig. 15 is across-sectional detailed view of a carton showing the locking meansillus trated in Fig. 14.

A selected embodiment of the invention are folded so as to leaveapertures and 31,-

thereby leaving a projection 32. This projection as will be laterdescribed, serves to engage with a member on the inner casing whichslidably sup orts a bulb.

Portions 26 and 2 are each provided with scorings 33 and 34 so that whenthe blank is formed, the members 28 and 29 will be creased centrally andform support member disposed in the corners of the carton to hold theprojection 32 away from the wall thereof. It will thus be seen that whenthe carton is set up the portions 26 and 27 which arescored at 33 and 34will be provided with flaps 35 and 36' which will be disposed adjacentto the inner walls of the carton, i. e.. the flap 35 will be disposedagainst the wall 21 while the flap 36 will be disposed against the wall23. When the outer casing of the carton is, therefore, assembled and theextension 25 is glued to the edge of the wall 24, the portions 26 and 27Will be so positioned as to provide the projection 32 disposed inopposite relation and spaced away from the wall thereof.

An inner casing 37 is provided in which a bulb is disposed for insertioninto the outer casing. This casing is formed from a blank 38 shown inFig. 11; the blank is so constructed as to provide a housing composed ofside walls 39 and 40 and upper and lower platforms 41 and 42respectively. The lower platform is provided with an aperture 43 throughwhich the contact members of the radio tube may project.

The platform" 41 is provided with an aperture 44to receive the upperportion of a bulb which projects slightly through the platform to beretained thereby.

The platform 41 is provided with an extension 45 having bracemembers 46and 47 ,casing is set up, it is folded along the scored portionsindicated in dotted lines so that when a housin is provided by folding,it may be secured y gluing a flap 55 to an edge of the side wall 40. Thebrace-members may then be folded inwardly and by reason of the inclinededges thereof, the portions 45 and 48 will project outwardly from theside Walls of the housing (see Fig. 5).

An article such as a radio tube, indicated by reference numeral 56 maybe positioned in the housing 37 so that the contact members 57 of thetube will project from the platform 42 of the housing and the upper end58 of the bulb will be disposed in the aperture 44 of the platform 41.

If desirable, an intermediate packing 59 may be employed in the form ofa corrugated cylinder as shown in Fig. 3 or if desirable, the corrugatedpacking medium may be a tube of rectangular transverse cross-sectionalform so as to lit the inner housing.

It will be evident that when the inner casing 37 is formed, a radio tubeor like article may be readily inserted therein. This 4 casing is theninserted into the outer casing and moved until the extensions 45 and 48pass over the projections 32. These projections being held outwardly bymembers 28 and 29 serve to engage the extensions 45 and 48 if the innercase is moved for removal from the outer casing. Thus the inner -casingis locked in position but at the same time, is movable a limiteddistance.

Normally, the inner casing is so disposed with respect to the outercasing that a radio tube will be fully protected by the outer casing asduring transportation. When it is desirable, however, to test a tubewithout moving it from the package, the inner casing may be moved sothat the contact pins of the article or radio tube will project from theouter casing, leaving the contactpins free for insertion into asocketfor the passage of electrical current through the tube.

It will, therefore, be evident that although the article is securelylocked against removal, it may readily be tested without interferencefrom the packing and by reason of the exposed upper end, the tube may beinspected for the passage of current through the filament, as whentesting a radio tube.

The foregoing description serves to illustrate a practical embodiment ofthe invention, but other modifications may be made therein, as forexample, a blank may be employed such as shown in Figs. 12 and 13comprising a sheet of material 60 adapted to constitute the walls of anouter casing. This sheet may be provided with a projection 61 providedwith a separator flap 62 and side members 63 and 64. When folded intooperative position as shown in Fi 13, the members 63 and 64 will liealong sitfes of opposite walls of the casing. The separator member 62will be bent inwardly so as to separate the projection 61 from a sidewall. This provides another form of lock for the same purpose as thatshown in Fig. 1.

Another form of locking means which will operate with the inner casingis shown in Figs. 14 and 15 in which a blank 65 may be used for thewalls of the casing and a projection 66 may be integral therewith.

The projection 66 may have an extension 67 disposed between two cut outsor slots 68 and '69 to provide extensions 70 and 71. When the projection66 is bent inwardly as shown in Fig. 15, the extensions 70 and 71 may bebent to hold the extension 67 away from the inner wall of the carton andthus provide a locking member for engagement.

with one of the members or 48 on the bulb holder or inner casing.

Although a preferred embodiment of the inventionis shown and describedherein, it is to be understood that modifications may be made thereinwithout departing from the spirit and scope of the invention as setforth in the appended claims.

' at is claimed is:

1. A radio tube carton comprising resilient supporting means movable.longitudinally thereof for holding a tube within the carton, means forlimiting the degree of movement of said supporting means within saidcarton,

and means for locking said supporting means to prevent removal of saidtube.

2. A radio tube carton comprising an outer casmg, an 1nner casingdlsposed wlthin and movable longitudinally of said outer casing,

means carried by said inner casing for supporting a radio tube and meansfor limiting the degree of movement between said casings. g

In testimony whereof, I have hereunto subscribed my name this 19thday-of July, 1927 HAROLD AMATEL.
